Abstract
Extra cellular enzymatic activities of mesophilic and thermophilic bacterial strains of hot springs of Dong area of Lohit district of A.runachal Pradesh have been studied. Bacterial strains of the spring water and sediments were assessed on Nutrient agar medium. Sediment samples consist of more thermophiles than mesophiles. About 66% of the isolates tested showed extra cellular enzyme activity. Out of 18 isolates screened, 9, 10, 12 and 4 isolates exhibited lipase, protease, amylase and cellulase activities respectively. This study showed that the bacterial strains of the thermal springs needs further investigations in view of their bioactive compounds and enzymes.
